Ερωτήσεις

How to install the plugin?

Installing the plugin is a very simple process. First, you need to download the plugin from the Web Expert membership area and save it to your computer. Then, on your website, from the WordPress admin area, go to “Plugins>Add New Plugin” and select “Upload Plugin”. Finally, you select the file you saved on your computer and select “Install Now”. For more information look up the corresponding README file that comes with the plugin or consult the plugin’s documentation.

Is it compatible with brand plugins?

Yes! Most branding plugins primarily use taxonomy to create the brand. In Web Expert Linkwise Affiliate Integration we give you the possibility to define taxonomies as properties. So we cover 100% compatibility with ALL plugins for brands.

Eligible for Linkwise?

We support both platforms. Web Expert aims to provide plugins that work seamlessly with all Linkwise requirements, possibly as soon as a new requirement is released, implemented, tested and released. However, many times its requirements change from store to store. You can contact us at support@webexpert.gr so that we can serve you further.

What can I do if I get an invalid license even though I entered it correctly?

First, you can try to remove the license key from the plugin settings, select save settings, and then enter it again.

In the event that the server that serves you blocks the communication to webexpert.gr, the license check cannot be carried out. You can contact your provider and ask to whitelist our IP addresses: 5.9.116.30 and 5.9.116.27.

Can my products have different availability terms?

Product availability can be set at the variations level. This means you can set different labels (Immediately available, Ship in 1-3 days), even on variations! However, it is not mandatory to define the field at such a depth. If the value is declared as default, it takes the value you selected in the product and correspondingly the plugin settings.

Can I hide some products from XML?

You can set various criteria to hide products, such as category, property or label, and a combination of these. For example, you can hide products that belong to one or more categories, belong to a property and have a specific label.

I have transferred my eshop from another platform and have a different product ID.

To serve the above need, you can declare the custom field that will derive the product ID, either through settings, or through a hook.

In the product code field (SKU) I have the code of my own warehouse and the supplier code in another field. How do I send the correct SKU/MPN?

You are given the ability to define any custom field or property to be printed on the MPN, via a setting or hook.

I have a large amount of data. What can I do?

The WooCommerce Linkwise Affiliate Integration plugin is programmed to generate the XML in its entirety and not in parts. This means it needs memory and power, depending on the products. However, it is built in a way to manage memory properly and has been tested on many providers with simple hosting packages and performs very well. To cover even the most demanding users, it is possible to run it through WP Cron, Scheduled Tasks (Plesk), Cron Jobs (cPanel) and crontab, to minimize memory requirements.

When generating the XML I get Error 500 or a technical problem or the XML says it is invalid.

As mentioned in the previous answer, the Web Expert Skroutz & BestPrice XML plugin is programmed to generate the XML in its entirety, not in parts, and requires memory and power, commensurate with the products. Try raising the PHP memory limit (WP_MEMORY_LIMIT) and max execution time (max_execution_time) on your server. Alternatively you can set the XML update via cron from the server. The commands you will use are mentioned in the next answer.

What can I do if the XML file does not refresh automatically?

You will need to check the operation of WP_CRON.
Alternatively, if you want the XML output via a cron job rather than WP Cron, you need to call the cron.php file:
e.g. php -d /home/domain/public_html/domain.gr/wp-content/plugins/webexpert_linkwise_affiliate_integration/cron.php

*Check the path of the cron.php file on your server

Is it possible to refresh XML via WP CLI?

In case you want the XML to be generated via WP CLI:

wp webexpert-linkwise-xml generate

What is the most likely reason why the XML file is not being created?

The most likely cause of the XML file not being generated is the memory limit compared to the volume of products. Please increase the memory limit, maybe the max execution time of PHP, on the side of the server that serves you.

What should I do if they ask me to see the entire category path?

Our plugin supports Yoast SEO primary category and Rank Math primary category, so it pulls this path from the category you’ve chosen as primary. Otherwise it fetches the first selected class, and if that is a parent, it cannot be seen as a path in the XML file. Alternatively, you will need to have only the final category selected

Why are discounts not showing up in the XML?

If you have passed offers or discounts dynamically (eg using a plugin) they cannot be retrieved from the XML as they are not stored in the database.

Why not set the “any size” option to display in the xml all the properties that participate in the variations?

The “any size” option should not be selected when you wish to display all variation properties. The correct way is to declare all properties on the variations in order for the store to meet Linkwise’s requirements. This is why there is also the size variation field so that it draws the corresponding stock from the size of each variation you have declared. You will need to select “generate variations from all properties” instead.

Which versions of WooCommerce is it compatible with?

Our plugin is compatible from version 6.0.0 and up.

Is it necessary to fill in the Linkwise Product ID?

You can fill in the Linkwise Product ID in case you want to track conversions, alternatively you can leave the “LinkWise Product ID” field to send only the XML of the products.

I have variations that are separated by color and Linkwise asks that they be declared as separate products.

The Web Expert Linkwise Affiliate Integration plugin automatically takes care of separating variations into separate products if it detects color as an attribute. If you have, for example, a blouse in 3 colors, the XML will show 3 products, with their corresponding available sizes.

Προγραμματιστές

If you want XML to output via cron job and not WP Cron, you need to call the cron.php file:

*Check the path of the cron.php file on your server
